Primero que nada, debemos tener una instalación actualizada de ImageMagick. En el sitio oficial se encuentran las instrucciones para instalarlo: http://www.imagemagick.org/script/binary-releases.php#macosx.

Luego copiamos el siguiente script en algún lugar dentro de nuestro filesystem. Por ejemplo en /usr/local/bin.

#!/usr/bin/env bash

# Source picture
FF=$1
FW=`identify -format %w ${FF}`;
FH=`identify -format %h ${FF}`;

# Watermark (must be a transparent background GIF or PNG)
WF=/path/to/watermark.png
GEO=+10+10
WXM=20
WW=`identify -format %w ${WF}`;
WH=`identify -format %h ${WF}`;

# Resizing watermark to 25% of source picture's shortest side
MX=$FH
if [ $FH -gt $FW ]; then
    MX=$FW
fi
WX=$[ $[ $[ $MX * 25 ] / 100 ] - ${WXM} ]

# Output filename
OF=`echo "${FF}" | sed -e 's,\.jpg$,-WM\.jpg,g'`

# Watermarking...
composite \
    \( ${WF} -resize ${WX} \) \
    ${FF} \
    -geometry ${GEO} \
    -gravity southeast \
    ${OF}

exit 0

Para ejecutarlo, simplemente se invoca de la siguiente forma:

Para que funcione el script, se debe uno posicionar en la carpeta en la que se tenga al menos 1 foto JPG, y ejecutar el script.

#!/usr/bin/env bash

DIR=`pwd -P`
W=720
H=$[ $[ $W * 2 ] / 3 ]
BITRATE=$[ $[ $W * $H ] / 64 ]
FPS=$1
FFMPEG=`which ffmpeg`

# Defaults
if [ "X$FPS" == "X" ]; then
    FPS=24
fi

I=1
for FILE in `ls -C1 ${DIR}/*.jpg`; do
    NEW_FILE=`printf "TL-%05d.jpg" "$I"`
    sips --resampleHeight ${H} ${FILE} --out ${NEW_FILE}.tmp.jpg
    sips --padToHeightWidth ${H} ${W} ${NEW_FILE}.tmp.jpg --out ${NEW_FILE}
    rm -f ${NEW_FILE}.tmp.jpg
    I=$[ $I + 1 ]
done

${FFMPEG} -r ${FPS} -b ${BITRATE} -i TL-%05d.jpg \
    -s ${W}x${H} \
    ${DIR}/timelapse-`date "+%Y%m%d-%H%M%S"`-${W}x${H}.mp4 

rm -rf TL-?????.jpg 

exit 0
